MACHINE FOR OPERATING ON IN SOLES.

Patented Aug. 1, 191

Application filed December 16, 1912. Serial No. 737,020.

State of Massachusetts, have invented cer-' tain new and useful Improvements in Machines for Operating on Insoles; and I do hereby declare the following to be a full, clear, and exact description of the-invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to machines for operating on insoles which are used in the manufacture of boots and shoes, and more particularly to machines for applying reinforcing fabric to insoles.

At the present time there are three types of machines for applying reinforcing fabric to insoles, namely, (1) machines for forming a bead or crimp in the reinforcing fabric and securing it to the insole, known commercially as gemming machines, (2) machines for preliminarily tucking the reinforcing fabric into the inside angle at the base of the lip prior to the gemming operation, known commercially as forming-in machines, and (3) machines for tightening the reinforcing fabric about the lip of the insole subsequent to the gemming operation, known commercially as rib-tightening machines.

The principal object of the present invention is to produce a novel construction and arrangement of tools for performing the rib tightening operation whereby the proper application of the reinforcing fabric to the lip is insured.

To the accomplishment of this object and such others as may hereinafter appear the features of the invention relate to certain devices, combinations and arrangements of parts, hereinafter described and then set forth broadly and in detail in the appended claims, which possess advantages readily apparent to those skilled in the'art.

The various features of the present invention will be best understood from an inspection of the accompanying drawings illustrated in the preferred'embodiment of the invention, as constructed for operating on Gem insoles in which- Figure 1 is a side elevation, the driving pulley being removed; Fig. 2 is'a detail, in side elevation and partly in section of the operating devices, a Gem insole being shown in operating-position; Fig. 3 is an enlarged plan; Fig. 4 is a detail, in plan and partly in section, of the hammer and fabric trimmlng knife; Fig. 5 is a plan of a Gem insole after being operated upon by the machine showing the manner in which the reinforce 1s trlmmed within the edge of the insole at the shank; and Fig. 6 is a cross-section of a Gem insole before being passed through the machine.

In the embodiment of the invention illustrated in the drawings the work support, upon which the unribbed or grain side of the insole rests while it is being operated upon, consists of a flat, horizontal disk 1 (Fig. 1) mounted upon the upper end of a short shaft 2 jou'rnaled in bearings 3 formed in a yoke 4: secured to the machine frame. The lower end of the shaft 2 is connected to a reduced rod' 5 which is connected in turn to a treadle rod 6, manipulation of which by the operative lowers the work support 1 against the tension of.a spring 7 coiled around the rod 5 and interposed between a stationary part of the yoke 4L and a part carried by the rod 5. The Work support is positively, driven, during the operation of the machine, through a gear 8 splined to the shaft 2 and engaged by a gear 9 carried by an inclined shaft 10 the lower end of which is journaled in a long bearing formed in the machine frame and the upper end of which is journaled in a bearing 11 formed in the machine frame. driven from a horizontal, transverse driving shaft 13, journaled in bearings formed in Y the machine frame, through a worm gear 14:

on the shaft 10 and a worm 15 on the shaft 13.

The devices for operating on the insole supported on the work support to tighten the reinforcing fabric into the angles at the base of the lip consist of an inside tightening tool comprising a roll 16 (Figs. 1 and 2) having a thin edge arranged to press the reinforcing fabric down into the inside angle at the base of the lip and a face of substantial area to press the reinforcing fabric against the inner side of the lip, and an outside tightening tool comprising a disk 17 having an edge arranged to press the reinforcing fabric down into the outside angle at the base of the lip. In addition to these tools there is preferably provided a hammer 18 operating outside the lip, to press the reinforcing fabric against the outer side of the lip, and cooperating with the face of the roll 16 to set the lip inward (see Fig. 2). The disk 17 also cooperates with the work support 1 in feeding the insole through the machine.

The roll'16 is mounted upon the lower end of a vertical stem 19 (Fig. 2) which is ournaled by means of a ball bearing 20 for free rotation in a chambered rod 21 slidably mounted in a carrier 22. The carrier 22 is provided with a horizontal block 23 which is slidably mounted on the flat top of a yoke 24 (see Figs. 1 and 3) loosely mounted on a stud 25 carried in a bracket 26 secured to the frame. The shaft 19 is forced clownward so as to press the roll firmly against the surface of the sole by a leaf spring 27, a slot 28 (Fig. 3) being provided in its free end which engages a tongue 29 formed on the upper end of the rod 21. The other end of the spring is secured, by a tap bolt 30, to the block 23. In order to limit the downward movement of the roll 16 under the influence of the spring 27, the block 23 carries a finger 31 (Fig. 2) which enters a recess 32, formed in the rod 21, through a slot 33 in the carrier 22. In order to permit the adjustment of the roll 16 toward and from the disk 17 to accommodate for different thicknesses of lip, the block 23 is provided with a slot 34 which embraces a tap bolt 35 threaded into the yoke 24.

The fabric tightening and feed disk 17 is secured on the upper end of the shaft 10 (Fig. 1) and is positively rotated during the operation of the machine through the connections, heretofore described, from the driving shaft 13. The rotary disk is provided with a face 36 for engaging the feather of the insole and a peripheral edge 37 for engaging the outside angle at the base of the lip. The hammer 18 is provided with a beveled striking face 38. The roll 16 is preferably frusto-conical in shape and is arranged with its broader base directed to-' ward the surface of the insole so that its face is substantially parallel to the striking face of the hammer. With the roll 16 and hammer 18 thus constructed and arranged they will act to compress the lip from base to top and bend and set the lip inward at an inclination to the surface of the sole so that it will stand at the proper angle to the bottom of the last for the convenient and proper lasting and sewing of the shoe when the sole is bent transversely in applying it to the curved bottom of the last in the assembling operation. The roll 16 is vibrated as the sole is advanced so that its edge will pound the fabric in the angle at the base of the lip and its face will pound the side of the lip against the hammer 18. To this end the yoke 24 is provided with a third arm 39 (Figs. 2 and 3) which is pivotally connected by means of a stud 40 to a link 41 pivoted in turn on a rod 42 carried by an arm 43 which is secured to a rock shaft 44 journaled in brackets 45 on the machine frame. Depending from the rock shaft 44 is a second arm 46 which is forked to embrace an eccentric block driven by an eccentric 47 on the shaft 13. Through the connection described the roll 16 is rapidly actuated during the advance of the sole, to pound the body of the lip against the hammer 18 and cause its thin edge to press the fabric firmly into the inside angle at the base of the lip. The hammer 18 is arranged to operate across the top of the disk 17 and is adjustably connected by means of the slot and screw con nection 48 (Figs. 2 and 4) to one end of a rectangular bar 49 mounted to slide beneath a cover plate 50 (Figs. 1, 3 and 4) forming part of the bracket 26. The other end of the bar is pivotally connected through a link 51 to the rod 42. Through the connections described the hammer and roll 16 are reversely vibrated simultaneously and continuously. In order that the reverse vibrations of the roll 16 and hammer 18 will simultaneously pound the opposite sides of the lip, the stud 40 which connects the arm 39 and link 41 is an eccentric stud (see dotted lines Fig. 2) and by turning this stud the relative times of contact of the roll 16 and hammer 18 may be accurately adjusted to secure the best results.

It is desirable, from a selling point of view, that the reinforcing fabric be trimmed on the feather at the shank along a line located within the edge of the insole. In the illustrated embodiment of the invention a fabric trimming knife 52 (Fig. 2), having vertical and horizontal cutting edges, is arranged to operate at the rear edge of the face 36 of the disk 17 in an annular recess 53 formed for its reception. The knife 52 is provided with a curved shank 54 (Fig. 4) projecting from a block 55 adjustably connected, by means of a slot and screw connection 56, to a horizontal knife carrier 57. The knife carrier 57 is adjustably connected, by means of a slot and screw connection 58, to a block 59 (Fig. 1), which is mounted to slide vertically on ways 60 (see dotted lines Fig. 4) formed on the bearing 11 and is held in adjusted position by a tap bolt 61. With this construction the knife may readily be removed to permit it to be sharpened and then adjusted in the line of feed on the knife carrier 57 to a position with its cutting edge on a diameter of the feed Wheel, whatever its variation in length due to wear. By sliding the carrier 57 across the line of feed on the block 59 the knife may be positioned with its vertical cutting edge against the rear edge of the face 36. These adjustments provide for positioning the knife so that it operates opposite the point at which the reinforcing fabric is most firmly pressed between the work support 1 and disk 17 by the spring 7. By vertically adjusting theblock 59 on the bearing 11 the knife may accurately be located in its proper cutting position relative to the disk face 36.

As heretofore pointed out it is desirable to trim the reinforcing fabric on the feather at the shank along a line located within the edge of the insole. As the feather is narrowest at the inside ball and widest at the shank, with an intermediate width at the toe and outside ball, the trimming of the reinforcing fabric on the feather at the shank along a line located within the edge of the insole may conveniently be secured by providing the disk 17 with a face 36 having a width somewhat less than the width of the feather at the shank.

In Fig. 5 a plan is shown of a Gem insole after having been operated on by the machine. In this figure L is the lip, set over on the insole as shown in Fig. 2. The lines C show the trimmed edge of the reinforcing fabric at the shank, the leather body of the insole, originally beneath the trimmed ofi margin of the fabric, showing at S. In Fig. 6 a cross section is shown of a Gem insole as it comes from the gemming machine. The defective application of the reinforcing fabric in the angles at the base of the lip is shown by spaces at X and Y. The effective treatment of the insole by this machine is well illustrated by a comparison of Fig. 6 with the insole shown on Fig. 2.

vVhile the invention is shown in its illustrated embodiment as operating on a Gem insole, it will be recognized by those skilled in the art that certain features of the invention are useful in operating on insoles in which the reinforcing fabric is not applied to both sides of the lip. For example, the novel means for tightening the reinforcing fabric in the inside angle at the base of the lip could be used for Economy insoles, as also could the devices for setting the lip inward. The invention is not, therefore, limited to use with any particular type of insole. While, also, the invention has been illustrated and described in connection with a machine for applying reinforcing fabric to insoles, adapted particularly to perform the rib tightening operation, it will be apparent to those skilled in the art that certain features of the invention, for example the fabric trimming knife, are not limited to use in a machine for performing a rib tightening operation, but may advantageously be employed in other types of machines for applying reinforcing fabric to insoles.
